Specification of Letters Patent.

Patented J an. 7, 1919.

Application filed March 1. 1918. Serial No. 219.761. Renewed November18. 1918. Serial No. 263.097.

To all whom it may concern:

Be it known that I, VVTILLIAM S. GRAHAM, a citizen of the United States,anda resident of Canton, in the county. of Fulton and State of Illinois,have inventedv certain new and useful Improvements in AgriculturalImplements, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to improvements in agricultural implenients andis. illustrated in connection with a machine designed for pulling beets,such machine comprising a frame and two pairs of supporting wheelstherefor. the forward pair of which is controlled for steeringpurpoeesby the lateral turning of the seat-support at the rear of the machine.In machines that traverse a field along rows of growing plants it isfrequently necessary, owing to irregularities in the rows, for themachine to be swerved from side to side and consequently requiresconstant attention on the part of the-operator. So turning from sideto-side makes it d flicult many times for the operator to properly s ghtalong a row or between two rows. If his seat is a pivoted one andconnected with the guiding means, as is very frequently the case, he isliable to be carried so far to one side as to preclude properobservation by him of the plants ahead with respect to which the machineis about to perform its work.

My invention has for one of its objects the connecting of the seat tothe frame in such manner that when turned toward either side of themachine the seat will have a tilting action which will so incline thedriver that he can easily keep h s eyes di= rooted in the properposition to observe the work being done. 'Furthermore, by reason of suchtiltirg action when the seat 1s turnedlaterallv, the driver is enabledto exert his strength to better advantage for controlling the steeringmeans when such means are connected with the seat frame, as they are inthe machine shown. Briefly stated. I accomplish this object byconnecting the seatsupport to the frame by means of an inclined pivotpin.

It is another object of the invention to provide an improved means fornormally holding the seat-frame in center position with respectto themain frame of the machine sons to a largeextent to counteract thetendency of the gu ding means (which in the construction here showncomprise a pair of caster-wheels) to divert the machine from a truecourse. By so holding the parts the driver is relieved to a large extentofthe labor now imposed upon him in preventing such movements. Brieflystated, the invention in this'particular comprises a bearing blockcarried. by the pivoted seat-frame, which blocks rests upon a stationarymember supported by the frame, one of such parts having inclined sidesso that lateral swinging of the seat-frame is restrained with aconsequent holding of the guiding means.

These objects I atta n by the construction and arrangement of partsillustrated in the accompanying drawings and hereinafter particularlydescr bed. That which I believe to be new will be pointed out in theclaims.

In the drawings:

Figure 1 is a plan view of a beet puller, showing my improvementsapplied thereto;

Fig. 2 is a side elevation of the machine.- the parts in both Figs. 1and 2 being in the position they occupy when the machine is inoperation;

Fig. 3 is a rear view of the machine;

Fig. 4 is'a detail, being a rear view of the rear arch member of themain frame and the drivers seat and its connections to said arch member,the seat being shown turned to one side as it would be when the frontwheels are angled, and

Fig 5 is a vertical section taken at line 1-1 of Fig. 3.

Referring to the several figures of. the drawings in which correspondingparts are ind cated by like reference characters,

indicates the side bars of the main frame which are connected at theirrear ends, in the construct on shown. by a heavy yoke or arch member 11.12 indicates two diagonally arranged standards suitably connected attheir upper ends to the suppoting frame and preferably in alinement withthe ends of the yoke or arch 11. such standards being rig dly secured tothe side bars 10 and the arch 11 by bolts. Each standard carries at itslower end a lifting blade 13. 1% ind cates brace bars, one for eachstand ard 12. said brace bars being secured to the side bars 10. 15indicates a wheel? arch journaled insuitable bracketsl6 secured to theside bars 10, upon the turned end portions of which arch are mounted apair of rear carrying wheels 17. 18 indicates a bellcrank leverpit-*otally connected with one of the frame bars 10 and having such contively, to the side bars 10. 23 indicates a tongue mounted for bothlateral and ver tical movement,the vertical movement being provided forby reason of the tongue being secured to a yoke 2 1 that extends betweenthe frame bars 10, the downwardly turned ends of the yoke being pivotedat 25 to such side bars 10, and the lateral nioveient of the tonguebeing provided for by reason of the tongue being connected to the yokeby means of a pivot bolt 26. Means are provided for raising the forwardwheels 20 and the tongue 23 and locking the tongue in place, but as suchfeatures form no part of my present invention, I do not deem itnecessary to here enter upon a detailed description of them. Suchdetailed description, however, is given in Letters Patent No, 1,261,227,dated April 2, 1918, granted upon an application filed by me.

The vertical axle members 2]., which carry the caster wheels 20, areturned at their upper ends to form laterally extending arms 27, and toeach of such arms is secured in any suitable manner a rod 28 thatextends diagonally to the rear where it is fastened in any appropriatemanner to one end of a pivoted cross-bar 29. Upon the turning of thispivoted cross-bar, it is evident that there will be exerted upon one ofthe rods 28 a pull, and a push upon the other, the result of which willbe the turning of the pair of guiding wheels 20 to deflect the course ofthe machine as desired. 30 indicates a heavy bracket bolted to thecentral. part of the rear arch member 11 of the main frame, andprojecting rearwardly therefrom. As shown (see Fig. 5), it is prO- videdwith a diagonal passage 31 therethrough, in which revolubly fits a heavypin 32, the incl nation of the o ening- 31 being su h that the upper endof the pin is (01- siderablv in rear of its lower end. As shown. thisheavy pin 32 is somewhat longer than the passage 31 so as to allow acertain amount of longitudinal mo ement of the pin for a purposehereinafter explained. The lower end of the rod is screw-threaded andreceives a nut 33, which retains in place the cross-bar 29 beforereferred to, said cross-bar being centrally pivoted upon the pin 32. Theupper end of the pin 32 is shown as being flattened so as to be adaptedto lie between the forward ends of two seat bars 3i (see Fig. 1), itbeingconnected to Such seat bars by a bolt 35. The drivers seat, whichis secured to the rear ends of these bars 34:, is indicated by-36. 37inclicates two brace rods, each connected at its rear end to the outerface of one of the seat bars 3st, and from thence extending forwardlyand downwardly to near one end of the pivoted cross-bar 29 to which itis suitably connected. In the construction shown, a single bolt 38connects the two rods 37 to the seat bars and also holds in place aspacing sleeve 39 interposed between and bracing apart the said seatbars. 40 indicates a block fixedly secured by a bolt 41 or otherwisebetween the said seat bars 3%, a short distance in rear of the point ofattachment of the heavy pin 32 of such seat bars. This block projectsdown below the seat bars, and its lower face is formed to provide twocam surfaces or inclines extend ing upward and la erally from itscenter, as clearly shown in Fig. 3, to adapt it to fit centrally andrest evenly upon the upper face of the bracket 30, which face, where itis in contact with the block40, is formed so as to present two inclinedsurfaces, each rising from the long tudinal center of t e block towardthe side thereof, as clearly shown in said Fig. 3. In other words. thebracket at this point furnishes a shallow and slightly angular recess,in which rests the block l0 whose lower or bearing face is shaped toapproximately correspond thereto. 42 indicates a pair of foot restssecured in any appropriate manner to the frame at opposite sides of thecenter thereof and pro jectintr rearwardly.

l/Vhen a machine of this character is in use. the unevenness of theground o er which the machine travels has a tendencv to divert themachine from a true course. first to one side and then to the other,making it difficult and fat guing for the operator who has to press h sfeet very hard a ainst the foot supports 12 in. order to counteract suchmotion. Bv providing the bracket 30 with the upwardly inclin d walls onits upper face and providing the b ock 4&0 that extends down from theseat bars and rests on such surfaces, the strain. on the operator isvery much relieved for the reason that the frictional engagement of theinclined surfaces of these two parts is such that the front guiding whees are quite strone'lv held a ainst turning. .Vhen, however. a turn ordeflect o fro i thedirect course is desired, t e frict onal resistancebetween the parts 30 and 40 is easily overcome by the drivertransferring his weight in large part from. the seat 36 to the footrests 42, as will be understood. With the weight thus largely removed,the block 40 will be able to readily move up one or the other of theinclined surfaces of the bracket, according to the direction in whichthe turn or deflection from a straight course is made. It is to allowfor the upward movement occasioned by the block 40 riding up one of saidinclined faces that the cylindrical bearing portion of the pin 32, asshown in Fig. 5, is made somewhat longer than the opening 31 throughwhich it passes.

As'heretofore constructed, in machines of thisgeneral hara ter whereinthe forward wheels have been turned through the turning of the driversseat, such seat has had its bars connc"ted to a verti"al pivot pin.While such a constru tion has been satisfactory so far as allowing aproper turning of the guiding wheelsis concerned, it has been objetionable for the reason that frequently the drivers seat would have tobe su'h a distan e laterally. as where the pivot pin is vertical. butwill have an upward movement as well as a lateral movement, whi h will.of course, tend to keep the drivers head in a position so that he cansight along the row. In operation, whenever it is desired to swerve froma direct line of travel, owing to an obstruction or an irregularity inplanting, the driver will press with greater force upon one foot support42 than on the other, and thus move the seat bars laterallv. which, ofcourse, through the rods 37 will cause the desired turning of thecross-bar 29, as usual, thus efi'e't ng a turning of the front wheels inthe desired dire'tion. In so doing, the drivers seat will not only becarried laterally, but by reason of the inclin tion of the pivot pin 32will be given quite a decided forward tilting as indicated in Fig. 4,and stl'h forward tilting will a1-o have a tendency to incline thedrivers body in such direction that he can, by turning his head, seealong the row being operated upon,' being assisted also in this by thefa"t that his seat is not swung as .far to one side as would be the caseif a verti al pivot pin for the seat bars were employed. Furthermore, byreason of not being carr ed so far to one side he is more easily enabledto exert his weight against that foot rest 42 which he tral position, asin Fig. 3, it will, as stated,

be of great assistance in preventin the usual sudden deflection of theguiding wheels from a straight course, as, of course, the weight of thedriver on the seat bars will make it a matter of cons derable ditfirultyto force the block 40 out of its central position and up one of theinclined surfaces on the upper face of the bracket..
